T0 all 'whom t mayr concern Be it known that I, EDWARD B. CLARK, citizen `ofthe United States, residing at Golconda, lin the county -of rPope and State `oi Illinois, have invented'certain new and use- -ful `Improvements in Station Indicators;

'and rheadoes hereby declare `that the following is a full, clear,:andk exact description of the inventiomfwhich z will enable others skilled in the art to which it appertainsvto make and .use the Ssame. Y

.This *invention `relates to station indicators. It relates more particularly -to a cabilnet for eusel on fstreet cars or trains having therein an :endless curtain or belt upon 1 ewhich'fthe namesoi' the various stationstops .are shown, certain :mechanism being emvployed which is adapted to operate saidA cur- .tain,.eithertoindicate successively all stops or. stations, or vtor indicating only imporvltant stations 'Where limited trains rstop.

An object 'of the invention is tol vfurnish a station indicator for street ralljway cars or steam roads that can lbei-used to indicate local stops or such .stops as Vit may be the lWish yobli' the operator 'to show.

Another object is to furnish alstation indicator Ythat canbe adjusted to indicate ilocal or limited-'stops and which also can be revlerseldatV will :so vas 'to be of use .on trains running in veither direction.

The invention, in addition to this', relates --to certain details of constructiony and novel arrangements of parts as will be fully brought out herein.r

Inthe appended-drawing', forming a part of this'application, n' p i `Figure I 'shewsmy station indicator in perspective. J

Fig. Q'is a front `elevation of the 'same on a largerscal'e with the front sido. removed.

I Fig. '3 isv aside. elevation* of certain parts of the; operating mechanism.

Fig. 4 is a side elevation of the cabinet.

'Fig 5v is a ldetail of a toothed belt; and, Fig. 6 is a horizontal'section of certain parts ofthe cabinet and some of the operating mechanism.

vA indicates the cabinet and B its front -p'rovidedlwith aslot C through which extends an operating y lever D.

E and F representv certain openings or Wimi'ovvs:inthe front B.' through which to viewthe station names land other matter to be. exhibited. G isA an endless belt mounted upon rollers.' H supported; bearings in.

the cabinet in any suitable manner, the shafts J upon Whichthe rollers are `mounted each carrying a pinion gear K with each of which meshes a gear L mounted upon shaftsM.

Uponeach of said Ashafts M,which are Thelever D, beforementioned, is'mounted on a Vshaft yD within the casing, one of its ends beingsupported in a cross member D2, for example, see Fig. 6. The inner end of saidlever carries two pawls which are pivoted Vto it and are indicated by the letters S T, the pivot for the lever constituted by the shaft D lying midway between the pivots of said pawls. A spring U bears upon the pawl T and constantly tends to move it in the direction of and into engagement'L with the belt O, while a spring V controls the vpawl Sfor the same purpose. The said pawl S has an extended end W beyond'its pivot and 2 is a cam secured on a shaft?) which at its outer end extends ythrough the Wall of the cabinet, its inner end being seated in a socket l in the end of the said shaft D, a suitable key 5 holding said pin in place, there being a finger piece 6 on said shaft 3 outside of the cabinet. The said cam Y' is adapted when in one of its positions, as shown in full lines in Fig. 3, to engage the pawl T for moving it outward away from the belt. Likewise when in another position it is adapted to engage the extension. of

the pawl S and accomplish the same purpose while permitting the pawl T to engage the belt, it being the purpose, as may be seen,

to hold one or the other of the pawls out of engagement while the other is in use.

7 is a spring attached at one end to the lever D inside the cabinet, its other end being attached to the said cabinet, forexample, the purpose of which is to hold the lever in its raised position, any suitable stop being used such, for instance, as the upper limit of the slot C in the front of the cabinet, to limit the raising movement.

8 indicates a series of holes in the end wall of the cabinet asl shownin Figs. 1 andwill be indicated in successive order.

4 in anyone of which a pinv 9 may be inserted to lie in the path of downward movement of the said lever D.` 10 is a guideYV within the cabinet being mounted in any suitable manner parallel to and behind one of the stretches of the belt O, said guide` being supported in any suitable manner as by 11, for example, Figs. 2 and 8. l

As has been stated in the objects, my purpose is tofurnish a station indicator that can be lused to indicate local stops in successlve order and which 1s reversible 1n its operation so as to be of use in either direction of travel of the train, and to convert the same so that it maybe used for limited stops, or so as to indicate only widely separatedfstation stops, an adjustment in the cabinet being made to accomplish these purposes as will now be understood.

The movement ofthe lever D, whichis al- -ways a downward one, will operate the belt or curtainG; through the belt 0 by means of the pawls S'T, the movement of the said belt O being in either direction according to whichl pawl is in engagement with it, it being observed that since the pawls are located atopposite sides of the pivot (the shaft D) the downward movement of said lever will transmit 'movement in either direction to saidbelt O. The extent of movement imparted to the latter is according to the particular adjustment of the pin 9 in the holes 8. For instance, `if the said pin is inthe highest hole 7 the limit of movement may be only such that each local sop I it is-desired to show limited stops opposite the window E the pin 9 may be adjusted to the proper hole, any one -hole corresponding'to a given station, so thatthe operator, know- 'ing this, shows the proper stop at the winf. In order to have a considerabledistance of movement of the 'belt or `curtain G with a small amount of travel of the pawls S T, the shafts J are preferably geared up by the use of the pinions K and the gears L already described. However, it is clear that va greater separation of the pivots ofthe pawls will also produce more movement of the curtain G in a given movement of the lever D. Y

As an advertising featureithe curtain or belt G may be `provided opposite the names of the station stops with names yof hotels or business houses which may be brought for limiting the yeXtentof Vthat movement.

opposite thewindow F, as the station stop to which it corresponds comes opposite the window'E. The advantage of being able to produce in a single device means by which local stops and limited stops may be shown in either direction of travel will be appreciated.

'IheV guide .10 acts as a firm backing for the belt O and receives the pressure of the latter due to the pressure ofthe vpawls thereon. i.;

It is'not'my wish to be confinedto the exact arrangement* shown and described herein since there maybe some veryslight changes made that` will still lie .withinpthe 80 the accompanyingclaims. Y .7 Y Having thus described-'my invention, I claim:-'-; e. f x a t 1. In a station indicator,the combination of' a traveling -curtainrorbelthaving station stops .indicated'thereom means toV opcrate it includin an endless yiieXible-,t'ravely ing'member, a fever pivotally mounted,L apawlpivoted to the lever at each side of the V90 pivot thereof, andl separately adapted to engage'andl impart movement to the member in Veither direction, andimeans Acarriedbyr thelever adapted to reverse the positionsv of vi the pawls whereby the direction of travel of meaning of the invention and the' scope of Vsaid curtain or belt may be reversed.

2. TheY combination in a .stationindicator, ofa belt or curtain havingy station stops provided with a series of teeth, a'pivotally mounted lever, a` pawl pivoted to thev lever at each side of its pivot and each adapted to engage the said belt, means carried by thel lever adapted tof'bemoved to twodiii'er- 105 ent positionsY whereby to disengage one of the pawls -fromsaid belt andy permit. the other to engage,rand a stop adapted yto be placed in the path of movement of the leverV 3. In a station indicator, the combination vof lanendlessubelt having vstation stopsV indicated thereon, mechanism to carryrand impart movement to said' Abelt including a 1 ,toothed belt, a pivotallymounted lever, a 115 pawl pivoted thereto at eachside of'itsipoint of support, each said pawl adapted to'ielastically engage said toothed belt, a guide to receive the latter againstY it, and means i adapted t0 reverse the positions of thepawls 120 .on thek said toothed belt wherebytoY vreverse the direction of its movement. Y i i 4. Ina station indicator, the combination of anendless belt having station stopsindicated thereon, mechanismv to carryand impart movement to said-belt including a toothed belt, .a pivotally mounted lever, a

`pawl pivoted :thereto at: each side'ofuits point of support, Veach saidlpawla'dapted to -Y elastically engage-saidtoothedbelt, a guide to receive the latter against it, means adapted to reverse the positions of the pawls whereby to reverse the direction of the movement of said belt, and a stop adjustable to different positions adapted for limiting the extent of movementv of said lever.

5. In a station indicator, the combination with a belt having a series of station stops indicated thereon, gearing to operate the same including a pair of spaced Wheels, a flexible member trained over said Wheels, said flexible member including a series of equally spaced portions, a single lever pivotally mounted, a pair of pavvls pivoted on Copies of this patent may be obtained forpve cents each, by addressing the said lever, one at each side of the pivot of said lever, said pavvls adapted to separately engage the described spaced portions of the flexible member, and means engaging 4the pavvls adapted to change the operative position of the same whereby in the movement of the lever the described flexible member may be operated in either direction.
